secondly, arranging binding steel bars and wire pipes in the template, and cushioning a protective layer concrete cushion block on the PE platform, wherein the strength of the concrete cushion block is equal to that of cast-in-place concrete;
thirdly, pre-burying pre-buried nuts for hoisting and connecting in the template;
Fourthly, arranging cold-drawn reinforcing mesh at the reinforcing reserved at the upper opening of the template;
Fifthly, pouring concrete with the strength not smaller than C30, and leveling the surrounding after vibrating;
step six, heightening 7 cm templates inwards 20cm around at two sides;
Seventh, arranging heating pipe pieces with upper inlets and outlets in the template, and lifting the heating pipe pieces by 2 cm by adopting a support cushion block; the inlet and outlet of the heating pipe are reserved at the reserved holes on the template, and the inlet and outlet of the heating pipe are temporarily plugged;
eighth step, placing polyethylene foam bars or polyethylene foam blocks between the heating pipe pieces;
ninth, pouring plastic foam concrete or light ceramsite concrete;
step ten, after the initial setting of the concrete, carrying out floor surface collecting or directly pasting floor bricks;
The construction and installation method of the assembled integral floor slab comprises the following steps:
The first step, an adjustable supporting device is adopted as a supporting structure of the floor, independent support is adopted to be adjustable, a horizontal connecting rod is a fixed socket member, and the contact part of the independent support and the floor is required to be increased by a wood cushion block to prevent the damage to the floor;
Step two, the supporting structure at the floor installation position is adjusted to a horizontal datum line before the floor is installed, and a positioning control line for the floor installation is arranged, so that the floor deviation dislocation in the installation process is prevented;
Thirdly, installing a floor slab hoisting device on the embedded nuts of the hoisted floor slab, and tightening the floor slab hoisting device by bolts, wherein the hoisting device is made of square steel into a stretched cross shape;
Fourthly, hoisting in place: lifting the floor slab member to the upper part of the installation position by lifting equipment, wherein the height is not more than 10cm, manually adjusting the floor slab member after approaching the installation position, and adjusting the control line position of the floor slab member; if the floor slab is assembled, a tongue-and-groove is arranged between the two floor slabs, cement structural adhesive is firstly brushed in the tongue-and-groove, and after the floor slab is assembled, the floor slab connection and the adjustment steel plate are added in the embedded inner nuts of the grooves of the floor slab, so that the floor slab becomes a whole;
Fifthly, connecting and fastening the floor slab in place by adopting a supporting and positioning device and a support; the steel bars protruding around the floor slab are used for anchoring by extending into the shear wall or the ring beam of the assembled integral filling wall, and binding and concrete cast-in-situ are carried out by adopting stirrups and ring beam steel bars.
